Compressed air lines
Of course, it is possible to control vibrators by varying the air pressure or air volume. However, please ensure
that the compressed-air units are correctly dimensioned. Quick-release catches are used for connection to the
knocker and to the pneumatic control system.
Knocker
The special feature of this newly developed knocker is broad-band coverage of the impact force adjustment
range and interval adjustment range. This has been made possible by an operating pressure of 2-7.5 bar. The
impact force can be set pneumatically and/or also mechanically. The knocker can thus be used very flexibly.
Pneumatic impact force:
Mechanical impact force control:
The knocker is supplied with a base plate used to attach the knocker and transmit the impact force. The
knocker housing and knocker base plate are made of aluminium. The impact plate (integrated in the base plate)
is made of special-purpose impact-resistant plastic.
Field of application
Intermittent compressed-air knockers can be used to dislodge material adhering to container walls (e.g. silos,
hoppers, filter outlets, reactors and pipes).
The knockers can be used in wet areas, in explosion-hazard areas or in the open air.
Mechanical construction and mode of operation
On all intermittent knockers, a piston is forced against a spring by means of compressed air. When quickly
vented, the piston is shot against a surface. On the FKL, this is a baffle plate which is a part of the device.

by setting the pressure range between 2 and 7 bar. (PTR)
by fitting and setting the threaded rod with lock nut (remove socket-
head cap screw on the knocker end cap beforehand), it is possible to
restrict the stroke of the piston, thus reducing the impact force. Always
screw in or unscrew the screw with the system depressurised.
